To all whom it may concern Be it known that I, THOMAS H. CARROLL, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State ofv Pennsylvania, have invented new and useful Improvements in Looking Devices, of which the following isa specifi cation. I p

My invention relates to new and useful improvements in locking devices and has for its object to provide an exceedingly simple and effective device of this character whereby two members may be readily and quickly locked together or unlocked or when desired.

Another object of the invention is to pro vide a locking device particularlyadapted to be used at places where the parts may be concealed but which may be readily manipulated when the parts are accessible;

A further object of the invention is to' provide a locking device for separable supporting members or brackets, such as holders for rolls of goods to'be dispensed,as for instance rolls of toilet paper, paper towels, cloth, oil cloth or other" goods generally made up into rolls. V p

With these ends in View, this invention consists in the details oficonstruction and combination of'elements hereinafter set forth 7 and then specifically designated by the which Figure 1, is a side elevation of myim provedv locking device illustrating its use with a toilet paper roll holder, parts thereof, being shown in section and illustrating apaste board tube in section and partly broken away on which'the-toilet paper is wound.

Fig. 11, is an end ing member, and i s Fig. 12, is a section Fig. 11. f g In carrying out my invention as here-embodied, 2 represents a base plate which is adapted to be attached to an object, such as a wall in any suitable and well known maninner end View of' the other view of the spring lockented Ju y 1911s. Application filed August 21, 1917. Serial No. 187,388. r Y

at the line 12 12 of:

ner and intermediate its ends said base plate is provided with a flange 3 on its two opposite edges to form trackways and at one" i end of these trackways is inserted afoot 4 of the statlonarybracket 5, said foot being fixed to the base platein any suitable manner as by spot welding. Adj acent the outer end of the bracket 5 and on its inner face is fixed a'disk 6 having a central opening 7 which alines with the hole 8 in the bracket: and this disk carries stop means, such as an outwardly projecting lug on lugs 9. l i The reference numeral 10 represents amtatable barrel open at its outer end and adapted to inclose the disk'6 and this-outer. end is provided with'an outwardly projecta ing flange 11 adapted to engage the inner face of the bracket 5. This barrel carries a tube 12 located in said barrel and attached to its outerend, said tube having a central bo're13 on two different diameters, the larger I 1 diameter being at the inner end of the barrel and forms a chamber 14 for a purpose to I be hereinafter described.

A number of resilient or spring holding springs 15 are formed integral with the bar-' rel 10 by partially'cutting sections of the 7 7 the opening 7 and the-hole 8 which, is them secured to the bracket '5 in any suitable and well known manner as by h'eading-theendof said rod as shown in Fig. 3. The rod 16 carries a pin 18 some distance "from its end of attachment and this pin'coacts with the shoulder 19 formed by the difference in diameters of the central bore 13 and the chamber 14: thereby preventing longitudinal movement of the barrel but permitting the same to rotate upon a locking rod and this barrel further carries a stop lug 20 coacting with the stop means ,9 to limit the movements of said barrel, the same being normally forced in one direction by means of the helical spring 21 coiled about the, tube 12 and having one end attached to the bracket or the disk 6 carried thereby as the stationary member, the other end being fixed to the barrel as the movable member.

At the opposite or free end, the locking rod 16' is provided with the conical head and on this red 16 between the pin 18 and thehead'22 isslidably mouuteda sleeve 2-: which acts as a key and the end oi? said hey sleeve which coacts with the head is beveled inward toward its end as at and the extreme end of this sleeve is slightly larger in diameter than the largest por ion of the conical head it the other end of the trackways is slidably and detachably in serted the foot l of the separable or remow able bracket 26 to the-outer end of which is fixed another barrel 27 having an ere terior flange 28, whereby said barrel may be fastened to the bracket in some suitable and well known manner as by spot welding. The inner end of this barrel is provided with a hole for registration with the locking rod 16 and its key sleeve and in this barrel is mounted the spring locking member 30 plainly shown in Figs. 8 11 and .12. The locking member 30 con J of a body or disk 31 having a central o" surround d by an integral riveting flange l" whichis adapted topass through 29 in the barrel 2. then turned o beaded as plainly shown in Fig. the body 31 projects a pair of oppositely disposed resilient or spring arms 34 converging toward their treeor outer ends and these arms are adapted to pass over the conical head of the locking rod and drop behind the larger or base portion Of said head to prevent the removal of said locking inem-' her from the locking rod will be obvious.

In Fig. 10, I have shown a slightly different construction ot'spring locking member in which the riveting flange is dispensed with, and in this form of the device a hol' low or tubular rivet 35 is used for fastening the spring locking member within the barrel 27. The rivet is provided with a head or flange at one end and when the spring locking member is so locked that the hole 32 is in alinement with the hole 29 in the barrel,'the ring is inserted from the inner or backside and passed through these holes and then flanged or beadel on the outside as plainly she. .1 in F g. 10.

T will describe the'worh provedlocking device in 00 ot my imunction with atoilet paper roll holder in order that the by the spring members or fingers lo the: toy attaching the roll of paper to the l. :rrel 10 so that they vill rot ate together. 'i he separable bracket 26 then placed in osition by inserting the foot inthe end. of the traekway on the base plate and as rable bracket 26 is moved to itr-2prop r. i tion, the opening 20 in the barrel 2? w. registerwith the locking rod 16 and at same time the barrel 27 will pass into other end of the base board tube 36 of roll of paper. i

t In positioning the separable bracket 26, the ends of the resilient or spring fingers 3% will pass over the conical head ot the locking rod and snap down behind the larger or base portion oil said head in the region of the neck thereby securely locking the separable bracket in position, and

if any attemptis made to force the sepa-' rable bracket 26 Etroro the base plate, the spring fingers 3+: will be caused to more firmly grip the locking rod 16 because of their angular positions. As the paper withdrawn from the roll, the barrel 10 will be rotated ther with agaii :t the action of the spring 21 which will increase the tension of said spring to such degree that a portion of the paper will. be torn from the roll at the first or second row of perforations or the barrel will. come to a ston which will cause the paper to be torn thereby reducing to a minimum the possibility of anyone removing a g t :nnount of the paper'and preventing wastetulaessf (is the roll of paper is securely locked in place, the entire roll cannot be reit'ioved at one timeand stolen, and as the paper cannot be unwound without a great amount of trouble with its at tendant loss of time, it is unlilrely'that anyone would attempt to remove an entire roll of paper when-placed. in the holder constructed inaccordanee with my improve ment.

used or-removed, the cardboard tube filfiimay be readily torn from the holder which will give access to the key sleeve 24:, then by moving said keysleeve toward the free end or head 22 ot the rod-16, the beveled end 25 of said key sleeve will enter'between the spring fingers 34c and supportthem apartbeyond the outer circumference of the largest portion of the conical head 22, there.-

When the entire roll of paper has been withdrawal of the separable bracket 26 at which time another roll of paper may be placed on the hole.

Of course, I do not Wish to be limited to the exact details of construction as herein shown as these may be varied within the limits of the appended claims without departing from the spirit of my invention.

Having thus fully described my invention what I claim as new and patentable is- 1.
